The question asked, verbatim: best vulnerability scanning tools for small businesses
Brands named, in the order the engine gave
- Intruder recommended
Intruder - my default pick for most small businesses.
- Tenable Nessus recommended
Tenable Nessus - the gold standard if you have someone technical.
- Nessus Essentials recommended
Two caveats: Nessus Essentials is free but capped at 16 IPs, which is fine for a very small office or a test, and Nessus Professional runs roughly $3,590-$4,790/year for one scanner.
- Nessus Professional recommended
Two caveats: Nessus Essentials is free but capped at 16 IPs, which is fine for a very small office or a test, and Nessus Professional runs roughly $3,590-$4,790/year for one scanner.
- OpenVAS compared
(Nessus vs OpenVAS 2026 (https://ethicalhacking.ai/compare/nessus-vs-openvas))
- Greenbone OpenVAS recommended
Greenbone OpenVAS Community Edition - the free option.
- Greenbone OpenVAS Community Edition recommended
Greenbone OpenVAS Community Edition - the free option.
- Community Edition recommended
Greenbone OpenVAS Community Edition - the free option.
- Linux recommended
Worth it if you have Linux comfort in-house and a limited internet footprint.
- Astra Security recommended
Astra Security - if your main risk is a web app or you need a compliance report.
- Qualys VMDR recommended
Qualys VMDR - only if you're already heading toward enterprise.
- Snyk recommended
Snyk - a different problem, worth naming if you write software.
- NinjaOne mentioned
Two things worth saying plainly: for most small businesses the bigger gap isn't scanning at all, it's patching - if you're not already managing OS and third-party updates centrally, a tool like NinjaOne or your RMM will reduce more risk than a scanner will.

The answer, as recorded
Here's what I'd actually recommend, roughly in the order I'd suggest trying them: **1. Intruder - my default pick for most small businesses.** Continuous external/perimeter scanning with an "autoscanner" that re-scans when new CVEs drop, plus a genuinely plain-English UI. Entry pricing around $149/month, and it's the one scanner on this list that's majority small-business by customer base (~58% of its reviews), so the product is designed for teams without a security hire. Strongest ease-of-use and support scores of the big three. ([G2 comparison](https://www.g2.com/compare/intruder-vs-tenable-vulnerability-management)) **2. Tenable Nessus - the gold standard if you have someone technical.** The biggest plugin library and the deepest authenticated scanning of internal assets. Two caveats: **Nessus Essentials is free but capped at 16 IPs**, which is fine for a very small office or a test, and Nessus Professional runs roughly $3,590-$4,790/year for one scanner. It's also a scanning engine, not a managed program - it tells you what's broken, it doesn't help you triage. ([Nessus vs OpenVAS 2026](https://ethicalhacking.ai/compare/nessus-vs-openvas)) **3. Greenbone OpenVAS Community Edition - the free option.** $0, no host cap, and real scanning quality. You pay in labor: feed upkeep, tuning out false positives, and building your own prioritization and reporting. Worth it if you have Linux comfort in-house and a limited internet footprint. Note Greenbone moved its *commercial* appliances to per-asset, quote-based licensing as of March 1, 2026 - only the Community Edition is still free. ([Nessus vs OpenVAS](https://cipherssecurity.com/nessus-vs-openvas/)) **4. Astra Security - if your main risk is a web app or you need a compliance report.** Scanner is $199/month or $1,999/year per target with 9,300+ tests; the $5,999/year tier adds human-assisted pentesting. The draw is compliance-ready output (SOC 2, ISO, PCI) and a cheap $7/week trial to kick the tires. Priced per target, so it gets expensive if you have many apps. ([Astra pricing](https://www.getastra.com/lp/pentesting-pricing)) **5. Qualys VMDR - only if you're already heading toward enterprise.** Excellent asset inventory and agent-based coverage, but pricing isn't public (expect a sales call) and its customer base skews mid-market. Realistically overkill under ~100 employees. ([G2](https://www.g2.com/compare/intruder-vs-qualys-vmdr)) **6. Snyk - a different problem, worth naming if you write software.** Scans your own code, dependencies, and containers rather than your network. Generous free tier. It complements, not replaces, the above. Two things worth saying plainly: for most small businesses the bigger gap isn't scanning at all, it's **patching** - if you're not already managing OS and third-party updates centrally, a tool like NinjaOne or your RMM will reduce more risk than a scanner will. And scanning your external perimeter is where the fastest wins are; internal authenticated scanning is a second phase.
